Paper Title:
Synthesis, Optoelectronic Properties of a New Photochromic Diarylethene Bearing Benzothienyl and Malononitrile Group
  Abstract

An unsymmetrical diarylethene derivative bearing both benzothienyl and thienyl moieties, in which a malononitrile group was substituted at the 5-position of the thienyl ring, was synthesized. This compound undergo a reversible electrocyclic rearrangement, generating strongly colored closed-ring isomer upon irradiation with UV-light which show nonfluorescence, while exposure to light in the visible range triggers the cycloreversion to the colorless open-ring form that exhibits strong fluorescence properties. This properties of molecular photochromism were developed that showed both photo switches and fluorescence switches. The erasable and rewritable photo-images on this photochromic diarylethene were successfully demonstrated. This developments are crucial for fundamental research and eventual technical application for high-density optical data storage.
